DSpace RoadMap
2009-2010
•
DSpace today thrives on contributions•
Direction driven by those able to contribute•
Roadmap is a synthesis of those directions•
Below are Ideas toward next releases•
Look for conclusions after this meeting2009
•
DSpace 1.5 and 1.5.1 as year began•
Maven build and overlay system•
XMLUI (Manakin) as well as JSPUI2009 – DSpace 1.5.2
• SWORD module/version 1.3.1 supporting the sword standard version 1.3
• Cocoon upgraded to 2.2
• Fix for the UTF-8 issues with the XMLUI • New authentication methods: Hierarchical
LDAP and Shibboleth
• Full update translations: German, Italian for both XMLUI and JSPUI and Ukrainian for JSPUI
• New translations for 1.5.x: Greek and Thai • Graceful resolver for urn in the item page
for the JSPUI
2009 – DSpace 2.0
•
Technology preview assembled for OR2009•
Subsequent incremental development•
Service manager integrated into DSpace 1.62009 – DSpace 1.6
•
Releasing Soon.•
Embargoes, Batch Metadata Editing, Statistics, and much more ...•
Covered by Stuart Lewis in following presentationDSpace N.X?
•
Leave aside the numbering:•
More service / component orientation•
More generalized data model•
Straightforward migrationIssues
Issues – Code migration
•
Modularity / Components•
Refactoring into the right ones•
Always 90% done•
Extensibility•
Best guesses lead to success (eventually)Issues – Data migration
•
Upgrading data model means updatingdatabase
• ... and in the worst case the content store - but not likely
•
Using a data model means changing the code•
... and perhaps evolving local procedures and authorizationIssues – Two UIs
•
Expensive to maintain two•
Tradeoff: double work vs mismatched features•
Neither is universally accepted•
JSPUI: dated, flawed organizationIssues – Service platforms
•
DSpace 1: None (implied, JVM,JSP, Cocoon)•
DSpace 2: Custom; Spring (or flexible)•
Gaining momentum: OSGi (outside DSpace)Issues – Dev community
•
Small (dedicated!)•
Varying availability•
Widely distributedSolutions – Code
•
Maven: Already improved in 1.5.x•
Refactor and repackage•
Sort out overlays•
Need best practice examples!•
Multiple overlays = unpredictable.Solutions – Data
•
Incremental migration•
New model alongside old data•
Augment data as required•
Move to new codeSolutions – One UI?
•
Inevitably XMLUI / Manakin?•
Resolve differences in embedded logic•
Provide migration for customized JSPUIs•
Subcommunities?•
Address problems real and perceivedSolutions – Svc Platform
•
Ensure DSpace 1.6 (2.0) Service framework stays current and plays well with othersSolutions – Dev Team
•
Get more committers?•
less tech / specialists?•
Share more components•
Rely on adjacent teams2010
2010 - Trends
•
Service framework: OSGi?•
Modularity (reuse from other projects)OSGi
•
Just another service framework?•
Embraced by Sakai and Fedora Repository•
“Proven” in Eclipse•
Bundles:•
Standard dynamic loading / unloading•
Evolving (domain specific) dependency / API standards•
Apache Model embraced by committers•
Voting by “PMC”: -1, 0, or +1•
Majority for procedural issues•
Minimum of (3) +1 for releases•
-1 can “Veto” a code change.•
Who becomes the PMC?•
Default: existing committersOpportunity
•
Directions and technologies of DSpace and Fedora are similar•
Pause and look at possibilities•
Join together and avoid disparate development effortsProposal
•
DSpace and Fedoracommitter communities consider and develop a
recommendation for aligning and integrating the DSpace 2 and Fedora Repository
TimeLine
•
4Q09 “Now”•
DSpace 1.6 release•
Release Manager for “next”•
What goes in “next”•
1Q10 “Develop”•
2Q10 “Push to Release”•
3Q10 ??Want to Discuss? After 1.6 (and into the evening)
